Balance of Miner Actor should be greater than or equal to the sum of PreCommitDeposits and LockedFunds. It is possible for balance to fall below the sum of PCD, LF and InitialPledgeRequirements, and this is a bad state (IP Debt) that limits a miner actor’s behavior (i.e. no balance withdrawals) Excess balance as computed by st.GetAvailableBalance will be withdrawable or usable for pre-commit deposit or pledge lock-up.

Fields

info: Cid

Contains static info about this miner

pre_commit_deposits: TokenAmount

Total funds locked as pre_commit_deposit

locked_funds: TokenAmount

Total rewards and added funds locked in vesting table

vesting_funds: Cid

VestingFunds (Vesting Funds schedule for the miner).

fee_debt: TokenAmount

Absolute value of debt this miner owes from unpaid fees.

initial_pledge: TokenAmount

Sum of initial pledge requirements of all active sectors.

pre_committed_sectors: Cid

Sectors that have been pre-committed but not yet proven. Map, HAMT<SectorNumber, SectorPreCommitOnChainInfo>

pre_committed_sectors_cleanup: Cid

allocated_sectors: Cid

Allocated sector IDs. Sector IDs can never be reused once allocated.

sectors: Cid

Information for all proven and not-yet-garbage-collected sectors.

Sectors are removed from this AMT when the partition to which the sector belongs is compacted.

proving_period_start: ChainEpoch

The first epoch in this miner’s current proving period. This is the first epoch in which a PoSt for a partition at the miner’s first deadline may arrive. Alternatively, it is after the last epoch at which a PoSt for the previous window is valid. Always greater than zero, this may be greater than the current epoch for genesis miners in the first WPoStProvingPeriod epochs of the chain; the epochs before the first proving period starts are exempt from Window PoSt requirements. Updated at the end of every period by a cron callback.

current_deadline: u64

Index of the deadline within the proving period beginning at ProvingPeriodStart that has not yet been finalized. Updated at the end of each deadline window by a cron callback.

deadlines: Cid

The sector numbers due for PoSt at each deadline in the current proving period, frozen at period start. New sectors are added and expired ones removed at proving period boundary. Faults are not subtracted from this in state, but on the fly.

early_terminations: BitField

Deadlines with outstanding fees for early sector termination.

deadline_cron_active: bool

pub fn allocate_sector_numbers<BS: Blockstore>( &mut self, store: &BS, sector_numbers: &BitField, policy: CollisionPolicy, ) -> Result<(), ActorError>

Marks a set of sector numbers as having been allocated. If policy is DenyCollisions, fails if the set intersects with the sector numbers already allocated.

pub fn put_precommitted_sectors<BS: Blockstore>( &mut self, store: &BS, precommits: Vec<SectorPreCommitOnChainInfo>, ) -> Result<()>

Stores a pre-committed sector info, failing if the sector number is already present.

pub fn get_precommitted_sector<BS: Blockstore>( &self, store: &BS, sector_num: SectorNumber, ) -> Result<Option<SectorPreCommitOnChainInfo>, HamtError>

pub fn find_precommitted_sectors<BS: Blockstore>( &self, store: &BS, sector_numbers: &[SectorNumber], ) -> Result<Vec<SectorPreCommitOnChainInfo>>

Gets and returns the requested pre-committed sectors, skipping missing sectors.

pub fn delete_precommitted_sectors<BS: Blockstore>( &mut self, store: &BS, sector_nums: &[SectorNumber], ) -> Result<(), HamtError>

pub fn has_sector_number<BS: Blockstore>( &self, store: &BS, sector_num: SectorNumber, ) -> Result<bool>

pub fn put_sectors<BS: Blockstore>( &mut self, store: &BS, new_sectors: Vec<SectorOnChainInfo>, ) -> Result<()>

pub fn get_sector<BS: Blockstore>( &self, store: &BS, sector_num: SectorNumber, ) -> Result<Option<SectorOnChainInfo>>

pub fn delete_sectors<BS: Blockstore>( &mut self, store: &BS, sector_nos: &BitField, ) -> Result<(), AmtError>

pub fn for_each_sector<BS: Blockstore, F>(&self, store: &BS, f: F) -> Result<()>

pub fn find_sector<BS: Blockstore>( &self, policy: &Policy, store: &BS, sector_number: SectorNumber, ) -> Result<(u64, u64)>

Returns the deadline and partition index for a sector number.

pub fn reschedule_sector_expirations<BS: Blockstore>( &mut self, policy: &Policy, store: &BS, current_epoch: ChainEpoch, sector_size: SectorSize, deadline_sectors: DeadlineSectorMap, ) -> Result<Vec<SectorOnChainInfo>>

Schedules each sector to expire at its next deadline end. If it can’t find any given sector, it skips it.

This method assumes that each sector’s power has not changed, despite the rescheduling.

Note: this method is used to “upgrade” sectors, rescheduling the now-replaced sectors to expire at the end of the next deadline. Given the expense of sealing a sector, this function skips missing/faulty/terminated “upgraded” sectors instead of failing. That way, the new sectors can still be proved.

pub fn assign_sectors_to_deadlines<BS: Blockstore>( &mut self, policy: &Policy, store: &BS, current_epoch: ChainEpoch, sectors: Vec<SectorOnChainInfo>, partition_size: u64, sector_size: SectorSize, ) -> Result<()>

Assign new sectors to deadlines.

pub fn pop_early_terminations<BS: Blockstore>( &mut self, policy: &Policy, store: &BS, max_partitions: u64, max_sectors: u64, ) -> Result<(TerminationResult, bool)>

Pops up to max_sectors early terminated sectors from all deadlines.

Returns true if we still have more early terminations to process.

pub fn check_sector_active<BS: Blockstore>( &self, policy: &Policy, store: &BS, deadline_idx: u64, partition_idx: u64, sector_number: SectorNumber, require_proven: bool, ) -> Result<bool>

Returns an error if the target sector cannot be found, or some other bad state is reached. Returns Ok(false) if the target sector is faulty, terminated, or unproven Returns Ok(true) otherwise

Draws from vesting table and unlocked funds to repay up to the fee debt. Returns the amount unlocked from the vesting table and the amount taken from current balance. If the fee debt exceeds the total amount available for repayment the fee debt field is updated to track the remaining debt. Otherwise it is set to zero.

pub fn repay_debts(&mut self, curr_balance: &TokenAmount) -> Result<TokenAmount>

Repays the full miner actor fee debt. Returns the amount that must be burnt and an error if there are not sufficient funds to cover repayment. Miner state repays from unlocked funds and fails if unlocked funds are insufficient to cover fee debt. FeeDebt will be zero after a successful call.

pub fn unlock_unvested_funds<BS: Blockstore>( &mut self, store: &BS, current_epoch: ChainEpoch, target: &TokenAmount, ) -> Result<TokenAmount>

Unlocks an amount of funds that have not yet vested, if possible. The soonest-vesting entries are unlocked first. Returns the amount actually unlocked.
